[0002] In the field of household wardrobes, when the wardrobe is in use, it is necessary to put a fragrance disinfectant into it to remove the odor on clothes that have been stored for a long time and prevent bacterial growth. For example, mothballs are one of the commonly used fragrance disinfectants. However, this direct placement method also has some disadvantages, that is, after the fragrance disinfectant is placed in a fixed position, it can only wait for it to evaporate at a certain rate, and its release rate and release position cannot be controlled. As a result, the fragrance smell in a certain part is relatively strong or even too strong, while the sterilization and odor removal effect in other places is not obvious, and it cannot be released evenly, and the fragrance disinfectant cannot achieve the best effect.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 9 As shown, the present invention provides a fragrance sterilization device placed in a wardrobe, comprising an outer telescopic support rod 100, which supports two sides of the inner cavity of the wardrobe;

[0038] The inner telescopic rod 200 is fixedly connected to the outer telescopic support rod 100 via a support assembly 500;

[0039] The outer telescopic support rod 100 is composed of a hollow column 102 and a hollow column 101 sleeved on both ends of the hollow column 102. The end of the hollow column 101 is movably equipped with a threaded knob 103 threadedly connected to the end of the hollow column 102. The outer end of the hollow column 101 is provided with a supporting foot 104 to support the inner wall of the cabinet.

[0040] The inner telescopic rod 200 includes a hollow column 4 202 and a hollow column 3 201 sleeved on both ends of the hollow column 4 202. The hollow column 3 201 is provided with a supporting foot 203 for supporting against the inner wall of the cabinet.

[0041] A porous tube 502 is connected between the hollow column 2 102 and the hollow column 4 202. The porous tube 502 is connected to the inner cavities of the hollow column 3 201 and the hollow column 4 202 and can release sterilizing fragrance gas to the outside. A sterilizing fragrance volatile agent 105 is provided in the hollow column 2 102 and can release sterilizing fragrance gas into the hollow column 1 101. The hollow column 1 101 is connected to the hollow column 3 201 through a connecting tube 106.

[0042] The outer telescopic support rod 100 can adjust its overall length through the outer threaded knob 103 and is supported in the cavity of the cabinet. The inner telescopic rod 200 is connected to the outer telescopic support rod 100 and supports the clothes stacked thereon through the support assembly 500. The sterilizing fragrance volatile agent 105 is arranged in the hollow column 102, and the volatilized fragrance sterilizing gas will flow into the hollow column 101, flow into the inner telescopic rod 200 through the connecting pipe 106, and finally be discharged in the middle of the cavity through the porous tube 502. There are multiple porous tubes 502 evenly arranged, which can occupy a larger release area in the middle of the cavity, and the diffusion is more uniform and rapid. The clothes thereon will not have the problem of excessive and strong fragrance due to the single-point release of the fragrance.

[0043] like Figure 3 and Figure 4 As shown, the support assembly 500 also includes a support rod 501 connected between the hollow column 1 101 and the hollow column 3 201, and no gap is provided on the support rod 501 for releasing the sterilization fragrance gas outward.

[0044] The support rod 501 is used to connect the outer telescopic support rod 100 and the inner telescopic rod 200 and support the clothes. It is relatively located on both sides of the inner cavity of the cabinet, so there is no gap for releasing the fragrance sterilization gas. At the same time, it is also for increasing its support strength.

[0045] like Figure 8 As shown, a layer of rubber pad is provided on the bottom angle plane of the supporting foot 1 104 and the supporting foot 2 203 .

[0046] The rubber layer is used for anti-slip purposes, so that the fragrance sterilization device is supported more firmly in the cabinet.

[0047] like Figure 1 and Figure 2 As shown, the fragrance sterilization device composed of the inner telescopic rod 200 and the valve 300 is arranged between each layer of the cabinet, and the hollow columns 101 on the fragrance sterilization devices between each layer are interconnected through the connecting pipe 2 400, and the sterilization fragrance volatile agent 105 is only arranged in the hollow column 2 102 on the fragrance sterilization device located on the bottom layer.

[0048] The fragrance sterilization device is provided on each layer of the wardrobe, which is used to receive clothes and release fragrance sterilization gas to each layer of the wardrobe. It is not affected by the partitions of each layer, which causes uneven gas release or is difficult to be reached by the fragrance sterilization gas. The sterilization fragrance volatile agent 105 located on the lower layer can volatilize through the outward diffusion of the gas, so that the hollow column 101 on the upper layer is filled with fragrance sterilization gas, and then uniformly released through the porous tube 502. There is no need to set too many sterilization fragrance volatile agents 105 to cause material waste and the defect of too high fragrance concentration.

[0049] like Figure 1-Figure 3 As shown, a valve 300 is provided at the end of the hollow column 101, and the connecting end of the connecting pipe 106 and the hollow column 101 is connected to the valve 300 of the hollow column 101.

[0050] The valve 300 functions as a valve, which can control the conduction or cutoff between the connecting tube 106 and the hollow column 101, thereby achieving intermittent release of fragrance by operating the valve 300 instead of releasing it all the time, thereby reducing the fragrance concentration.

[0051] like Figure 6-Figure 7 As shown, the valve 300 includes a housing 301 fixedly mounted on a hollow column 101.

[0052] A partition 302 is disposed in the inner cavity of the housing 301 to divide the inner cavity into two independent cavities, one large and one small;

[0053] A button 303 is elastically mounted on the housing 301 through an elastic member 304, and an outer end of the button 303 extends to a closing path of a cabinet door of the cabinet;

[0054] A second partition 305 is disposed in the larger independent cavity of the housing 301 and divides the cavity into two upper and lower parts;

[0055] The lower part of the space of the larger independent cavity is connected to the inner cavity of the hollow column 101. The valve 300 also includes a connecting column 306 and a rotating column 307 which are fixed to each other and are arranged in the shell 301. The circumferential surface of the connecting column 306 abuts against the partition 2 305 to isolate the upper and lower parts of the space in the larger independent cavity. A notch 3061 is also provided on the connecting column 306 for connecting the lower part of the space of the larger independent cavity and the connecting tube 106. The rotating column 307 is sleeved on one end of the button 303 to control the rotating column 307 to drive the connecting column 306 to rotate.

[0056] The above scheme is a gas isolation scheme for the fragrance sterilization device. If the fragrance sterilization device is always released at the same position, it will cause excessive fragrance at that position and cause discomfort to the user. Therefore, it is necessary to properly isolate the gas under certain conditions so that it is no longer released to the outside. The above scheme uses the button 303 set on the door closing path as a driving device. When the door is closed, pressing the button 303 drives the rotating column 307 to rotate. The button 303 limits it to only linear movement. The rotation of the rotating column 307 will drive the connecting column 306 to rotate. Since the cavity of the housing 301 has been isolated and the notch 3061 on the connecting column 306 is the only way to connect the connecting tube 106 and the hollow column 101, and the final stop position of the notch 3061 in the circumferential direction determines whether the connecting tube 106 can conduct the fragrance sterilization gas, when the notch 3061 is connected to the lower space in the larger independent cavity, the connecting tube 106 coaxially arranged and connected thereto can connect the hollow column 101 and deliver the fragrance gas to the hollow column 3 201. After pressing the button 303, the notch 3061 will rotate to a different position so that the connecting tube 106 is no longer connected, thereby achieving intermittent release of the fragrance gas.

[0057] like Figure 8 and Fig. 9 As shown, the rotating column 307 includes an arc groove 3071 and a straight groove 3072 opened in its inner cavity, the number of sets of the arc groove 3071 and the straight groove 3072 is the same as the number of layers of the fragrance sterilization device, and the ends of two adjacent arc grooves 3071 and straight grooves 3072 are connected, and the button 303 includes a guide plate 3031 fixed to the inner side thereof, and a protrusion 3032 is provided on the guide plate 3031 to be movably engaged in the arc groove 3071 and the straight groove 3072;

[0058] When the button 303 is pressed, the protrusion 3032 slides in each arc groove 3071 and the linear groove 3072 so that the rotating column 307 drives the connecting column 306 to rotate.

[0059] When the protrusion 3032 slides in the arc groove 3071 and the straight groove 3072, the protrusion 3032 rotates in the arc groove 3071, which can drive the rotating column 307 to rotate, thereby driving the connecting column 306 to rotate. Each time the button 303 is pressed when the cabinet door is closed, the cooperation between the protrusion 3032 and the rotating column 307 will cause the connecting column 306 to rotate in the same direction. The number of groups of arc grooves 3071 and straight grooves 3072 is set to be the same as the number of layers of the fragrance sterilization device in order to facilitate the subsequent switching. The cooperation of each group of arc grooves 3071 and straight grooves 3072 with the protrusion 3032 represents a different rotational position of the connecting column 306. When the connecting column 306 of each layer of the fragrance sterilization device rotates each time, the final landing position represented by the notch 3061 of each layer of the connecting column 306 is different.

[0060] like Figure 7-Figure 9 As shown, when the buttons 303 on each layer of the fragrance sterilization device are pressed by the cabinet door, the notch 3061 of only one layer is rotated to connect the lower part of the larger independent cavity with the connecting pipe 106, and the fragrance sterilization devices of the other layers are not connected.

[0061] Through the above design, the user will switch the conduction state of the connecting column 306 of each layer of the fragrance sterilization device by opening and closing the cabinet door during daily use. Only one layer of the fragrance sterilization device is turned on, which can be achieved by setting different initial deflection angles of the connecting column 306 and the opening size of the notch 3061. For example, when the fragrance sterilization device is provided with four layers, the opening size of the notch 3061 is one-quarter of an arc along its circumference. Initially, only the notch 3061 of one of the connecting columns 306 is connected to the lower part of the larger independent cavity, and the rest are located in the upper part of the space. And by opening and closing to switch synchronously, it can be achieved that only one connecting column 306 and the conducting connecting pipe 106 are turned on each time. The advantage of adopting the above setting is that the fragrance sterilization system can control the real-time switching of the release position of its fragrance sterilization gas following daily use. Instead of always releasing at the same position, the excessive concentration of fragrance at this position causes discomfort to the user.

[0062] After adopting the device, for example, if the user opens the cabinet door once in the morning and once in the evening to take out or store clothes, the user can switch the fragrance release layer by closing the cabinet door and pressing the button 303. The fragrance is released in the corresponding layer during the time when the cabinet door is closed during the day and at night. When the cabinet door is opened next time, the fragrance sterilization gas release layer will be switched to another position after the cabinet door is closed, thereby performing cyclic switching, so that each layer can obtain a reasonable fragrance release time interval.

[0063] In the above process, the ideal switching may not be achieved because the cabinet door is opened multiple times in a special short period of time. For example, it is currently released on the first layer, and should be released on the second layer after closing, but due to accidental frequent taking, the cabinet door is closed twice in a short period of time, resulting in release on the third layer or back to the first layer. This kind of influence is not a big deal, because the release of fragrance sterilization gas is a long-term and slow process, not just a few hours or days. In a long period, the release time of each layer of the fragrance sterilization device is roughly the same, so this kind of error can be ignored.

[0064] like Figure 6 and Figure 7 As shown, the second partition plate 305 is provided with two petals, which abut against the circumference of the connecting column 306, and the connecting column 306 is only located in the larger independent cavity.

[0065] Partition plate 2 305 is always in contact with connecting column 306, and is used to cooperate with connecting column 306 to isolate the upper and lower spaces to prevent the fragrance from leaking outward. In addition, this structure limits the displacement flow channel of the sterilization fragrance from the lower space of the larger independent cavity to connecting tube 1 106, and then to hollow column 3 201 through connecting tube 1 106.

[0066] The working principle and use process of the present invention:

[0067] The sterilizing fragrance volatile agent 105 is arranged in the hollow column 102, and the volatilized fragrance sterilizing gas will flow into the hollow column 101, flow into the inner telescopic rod 200 through the connecting pipe 106, and finally be discharged in the middle of the cavity through the porous tube 502. There are multiple porous tubes 502 evenly arranged, which can occupy a larger release area in the middle of the cavity, and its diffusion is more uniform and rapid. At the same time, it can also be used as a custom setting of the space in the cabinet. Through the mutual cooperation between the valve 300 and the cabinet door, the release rate of the fragrance therein can be controlled to prevent the defects of too strong fragrance in a single position and too weak fragrance in other positions.

[0068] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
